Comparative Study
Residual thoracic hypokyphosis after posterior spinal fusion and instrumentation in adolescent idiopathic scoliosis: risk factors and clinical ramifications.
A retrospective review of clinical and radiographic data from a single-center, prospectively collected scoliosis database. ⋯ There are 2 risk factors that lead to thoracic hypokyphosis in AIS: preoperative hypokyphosis and use of a 5.5-mm-diameter rod. A larger-diameter rod should be considered when planning surgery for thoracic AIS, especially when there is preoperative hypokyphosis. Despite thoracic kyphosis measuring less than 20°, these patients did not have decreased clinical outcomes as measured by the SRS-30 or SAQ.

A cross-sectional study. ⋯ A 25-item LSS symptom scale was developed, and its reliability and validity were confirmed.

Comparative Study
Comparative safety of simultaneous and staged anterior and posterior spinal surgery.
Analysis of population-based national hospital discharge data collected for the Nationwide Inpatient Sample. ⋯ Staging circumferential spine surgery procedures during the same hospitalization offers no mortality benefit and may even expose patients to increased morbidity.

Retrospective analysis of a consecutive cohort of 62 adolescent patients treated by posterior spinal fusion (PSF) with a minimum follow-up of 2 years. ⋯ In a large consecutive cohort, reduction of scoliosis by ST2R is a simple method that allows 70% of correction in the coronal plane, equivalent to screw instrumentations, and a restoration of normal thoracic kyphosis.
